    Questions about clutch replacement for 04 CTS-V

    I have an 04 CTS-V that I bought at 40k miles. I do not know if the original owner replaced any clutch parts or not before I had purchased it. I now have 75k miles on it, and have not really noticed anything wrong with the clutch, however it is a little more difficult as far as shifting goes, especially reverse.

    I'm wondering what are some signs of my clutch needing to be replaced? I've been thinking about buying the whole LS7 clutch kit, but don't want to do it if it's not needed.
    Thanks!

    Have you bled the clutch fluid?

    Re: Questions about clutch replacement for 04 CTS-V

    I doubt you need a clutch. But, there are two things you could do that may help you. First of all, check your hydraulic clutch fluid level. These cars are notorious for losing clutch fluid making shifting less than it can be. You could go one step further and have it replaced and bled. If you're still having problems, there are bushings that can be replaced in the linkage. There's a thread floating around by Cadzilla that is the most inclusive shifter bushing thread I've ever seen. Truly amazing.

    To check your clutch, drive about 50-ish MPH in sixth gear. Push the clutch pedal in, rev the motor slightly, then let the clutch back out somewhat abruptly. If it grabs with a jerk, then it's good. If it only slowly engages, your clutch is on its way out.

    If you do a new clutch, take a look at monster as I replaced mine with a LS7 set-up and hate where the pedal grabs,just off the floor sucks ass.

    Which Monster would you go with?
    Did you do the LS7 kit from Lindsey Cadillac?
    I have gear chatter and plan on getting a new flywheel, clutch, slave in the next few months

    The forum members here that have installed Monster Stage 3 clutches have had problems. On the other hand those with lower stage Monster clutches have not reported the same problems. For expample:http://www.cadillacforums.com/forums...-2-5-15lb.html

    I have a Monster Level 1 that will be getting installed into my '04 soon (hopefully this week); I'll report back once it's in.

    Your pedal never came up higher? I have an LS7 in mine and the pedal is perfect, I did bleed the heck out of it when I installed it.

    Monster Stage 2 here, very happy with engagement position with LS7 slave and/or Monster slave (engage at same point, not at bottom, not at top). Not grabby, easy to start from stop. And much better performance than the stock clutch/flywheel.

    Re: Questions about clutch replacement for 04 CTS-V

    My oem clutch was still going strong at 120k miles. the Dual Mass flywheel on the other hand was clunking like crazy.

    I replaced mine with the katech Twin Disk. It is expensive BUT you get OEM quality, and the performance of a twin disk. One of the best mods I've done to my car. It revs like crazy now. Was blown away by the difference. I should have done this mod a LONG time ago.

    Did you go with an OEM LS7 flywheel, or lightweight? What'd ya think of the upgrade? Can you feel a difference?

    If you over-torqued your pressure plate bolts, the fingers on the pressure plate will retract inwards and you'll always be stuck with an "on-the-floor" disengagement point. If I had to guess, you followed the LS7 Z06 user's manual, which specifies 15 lb-ft, 37 lb-ft, and 74 lb-ft star bolt sequencing (if you used torque specs at all).

    Through testing, I found that the LS7 pressure plate fingers begin to move inward right after you cross the 50 lb-ft threshold. At 74 ft-lbs, those fingers have retracted so far inwards that you'll be lucky to get the clutch disengaged at all. After having the transmission in and out of the car 7 times in the summer of 2010, I discovered that the stock CTS-V 52 ft-lb torque specification was just about perfect for the LS7 clutch swap.

    I recommend using blue locktite and torquing your pressure plate bolts to 50 ft-lb. I've been running that way for 12,000 miles with zero problems. Since I'm about to replace this clutch with a McLeod RXT, I can also provide exit data on the outgoing LS7 clutch, if requested.

    Fuzzy, you and a couple of other guys on here (PISNUOFF is one) amaze me with your tenacity on this stuff. My patience would've worn thin after the second time.

    This is my only car. So, for me, it's not a question of "do I want to get it exactly right"--I have to.
